Summary:
We propose a new method of ray-launching estimation for high-speed and highly accurate analysis of pilot pollution, which often occurs in the upper floors of high-rise buildings. Our method simulates radio signals that reach from distant base stations much faster than a conventional raylaunching method. The mechanism of the fast calculation is due to an adaptive object selection approach, which excludes objects that have limited effects on a radio environment in the upper floors of high-rise buildings. It is confirmed that our method can make a calculation more than 20 times faster than a conventional ray-launching method with almost the same accuracy for the case with high base station antennas.
